Low polymer wax

When evaluating Low Polymer Wax, you must focus on molecular weight, melting point, and viscosity. For industrial applications like PVC processing or hot-melt adhesives, a melting point between 100°C and 115°C is standard. Ensure the viscosity (measured at 140°C) aligns with your production needs, typically ranging from 10 to 1000 cps depending on whether it is used as a lubricant or a dispersant. Additionally, check the density (usually 0.91-0.95 g/cm³) to ensure compatibility with your polymer matrix.

Request a Certificate of Analysis (COA) for every batch. Key indicators of purity include the acid value (should be near zero for non-oxidized PE wax) and ash content (ideally <0.05%). High ash content indicates impurities that can cause yellowing or degradation in the final product. For high-end applications, ask for Differential Scanning Calorimetry (DSC) curves to verify the sharpness of the melting peak, which indicates a narrow molecular weight distribution.

Compliance depends on the end-use. If the wax is used in food packaging or toys, it must meet FDA 21 CFR 175.300 or EU REACH regulations. For general industrial use, ensure the supplier provides a comprehensive Material Safety Data Sheet (MSDS) compliant with the Globally Harmonized System (GHS). If sourcing from China via Made-in-China.com, prioritize suppliers with ISO 9001:2015 certification to ensure consistent manufacturing processes.

Lubricant Grade is essential for PVC pipe and profile extrusion to improve surface gloss and processing speed. Dispersant Grade is used in color masterbatches to ensure uniform pigment distribution. Emulsifiable Grade (Oxidized PE Wax) is preferred for textile finishing, floor polishes, and paper coating due to its ability to form stable aqueous emulsions.

The primary risk is product substitution, where suppliers provide lower-grade paraffin wax or recycled wax instead of virgin Low Polymer Wax. To mitigate this, request pre-shipment samples and use third-party inspection services (like SGS or Intertek) to verify the melting point and viscosity before the balance payment is made. Another risk is moisture contamination during sea transit; ensure the supplier uses moisture-proof woven bags with inner PE liners.

Chemical prices are highly sensitive to crude oil fluctuations. It is advisable to negotiate formula-based pricing for long-term contracts. For MOQs, while standard units are 20ft containers (approx. 16-18 tons), many premium suppliers on Made-in-China.com offer pallet-level MOQs (1-2 tons) for trial orders. Always ask for a tiered pricing structure where a 5-10% discount is applied for volume increases beyond 20 tons.

Low Polymer Wax is generally classified as non-hazardous for transport, but you must confirm this with the supplier's DGM report (Identification and Classification Report for Air/Sea Transport of Goods). Ensure the cargo is kept away from heat sources during transit to prevent caking or blocking. For shipping to regions with high humidity, specify the use of desiccants inside the container.

Utilize the Secured Trading Service offered by Made-in-China.com to protect your payment until delivery is confirmed. Always verify the supplier's Business License and Export Permit. Avoid making payments to personal bank accounts; ensure the beneficiary name matches the company name on the proforma invoice exactly.
